HANGLIFE Threaded Inserts for Plastic, M2.5 Heat Set Insert for 3D Printing Components and Plastic Parts - Brass Metric Knurled Nuts (100 Pieces)

I've found myself buying this brand in particular. They are good quality. I have bought large quantities from CNC Kitchen, but sometimes I've needed sizes I didn't have, in a hurry, so I end up in here - choose these every time. I don't put them in hot as I don't personally think that's a good idea. I fit mine using a toggle press and add they go in, you can see them rotating and effectively cutting themselves into the material. A royal pita to get out of something is wrong, so I know they work!

Using a flat end of a soldering iron at 450C made these slide into the PLA like a knife through butter!Probably better quality than the cheap M3 screws i use in them!

wish there were more of the M3 sizes

It works what more do you need to know

Used these in UPVC window frames to secure window screens - I've used heat-set inserts before and these are just as good as the ones I've used previously. Good kit with a decent assortment. The ones I haven't used will be good for stock.

These have now been used on several 3D models where inserts are needed. Fitting them using a soldering iron is very simple just take your time. Once fitted the inserts are very solid as look as you don’t over tighten them.

Good selection of inserts, they are of good quality and hold very well.I will just buy top up packs as required.

I’d never heard of heat set inserts before but the instructions for a 3D print design I was working on suggested them as a neat ‘factory finish’ look on an enclosure.I picked this kit up on Amazon as there was a decent selection of sizes at a good price and with next day delivery available.I was not disappointed - coupled with a compatible insert tip for my soldering iron, these look great!
